title: Gilvocarcins, new antitumor antibiotics. 3. Antitumor activity.
abstract: Gilvocarcin V, isolated rom a Streptomyces culture showed activity against experimental tumors such as sarcoma 180, Ehrlich carcinoma, Meth 1 fibrosarcoma, MH134 hepatoma and lymphocytic leukemia P388. In particular, 40% of treated mice survived for 60 days, after intraperitoneal administration of gilvocarcin V to mice bearing Ehrlich  ascites carcinoma. But it was marginally active against B16 melanoma and did not produce prolongation of lifespan of mice bearing Lewis lung carcinoma.
